Advice needed - looking to earn CS credits

[TwinMom]

Hello,

I am a prospective international applicant living outside the US with a background in economics. I have both BSc and MSc along with a few years of professional experience and I do not have a single college credit in Computer Science (CS).

I am looking to pivot into CS and Georgia Tech's OMSCS is my top choice currently for which I've already applied but my application will most likely be deferred to Spring 2021.
I need to take a handful of accredited core CS courses online to demonstrate objectively documented basic capability and knowledge in CS.

Below are the courses that I am looking to take:

C++ Programming (or Intro to CS in C++)
Java Programming
Data Structures & Algorithms
Design and Analysis of Algorithms
Databases

The list can be slightly different but I believe these are the most important courses.

What option is most suitable for me? I'd really appreciate your expertise and advice on how I can take these courses and earn CS credits quickly and affordably.

Thank you.

All those courses can be taken through Study.com but you'd have to check with Georgia Tech to see how  or if they transfer. Also, whatever hoops you'd have jump through as an International student.
